CIRCUIT-CLOSER FOR-SIGNALING APPARATUS.

SPECIFICATION forming part of Letters Patent No.1412,460, dated October8, 1889. i Application iiled July 8, 1886. Serial No. 207,150. (Nomodel.)

To aZZ whom, it may concern:

Be it known that I, GEORGE D.v BURTON, a citizen of the United States,residing at New Ipswich, in the county of Hillsborough, in the State ofNew Hampshire, have invented certain new and useful improvements incircuitclosers for signaling apparatus for railwaytrains, and for use inother places where such signals are desirable, of which the following isso full, clear, and exact a description as will enable others skilled inthe art to which my invention appertains to make. and use they same,reference being-had to the accompanying drawing, in which mycircuit-closer is shown in section on an enlarged scale, the battery,wires, and bell being shown in elevation on a smaller scale.

The obj ect of my invention is to provide an improved device whereby thecircuits of signaling systems may be closed, such circuitcloser beingespecially designed for use in train-signaling, but being well adaptedfor use in any system where an alarm is sounded or a signal made by theclosing of an electrical circuit.

Referring to the drawing by letters, A represents a battery or othersource of electrical energy, and B C are the wires forming the circu it.These wires lead from the battery to circuit-closer through any suitablebell or other alarm, as at D. The wires are secured in the binding-postsE F in any well-known manner, and have at their terminals two plates GH, said terminals being secured at their outer ends by screws-I J, whichpass through said outer ends into the binding-posts, as shown. The innerends of the terminals are secured to a' central tubular post K, made ofinsulating material, by screws m j. Between these terminals and saidinsulatingfposu'and sethe end of the plate M being bent at a pointfarther removed from the post than the bend of plate L, so that normallythe ends of L and M will be held out of contact with each other.

N is a rod having a slot n therethrough, which the aforesaidcontact-plates L M pass through, as clearly shown, said rod beingprovided with a suitable operating-handle-as, for instance,a ring O or acord P. The wires being electrically connected through the binding-postsand terminals with these contactplates, the circuit will be completedwhen these contact-plates are brought together by pulling up the rod Nand the alarm sounded ductors leading therefrom, of a circuit-closerconsisting of a frame having an insulated post, to which the terminalsof th'e circuits are connected, the`one terminal overlapping the otherand the two fitting in a notched rod, said rod terminating in a ring orhandle.

2. As anew article of manufacture, a circuitcloser consisting of a framehaving an insulat-ed post, to which the terminals of the circuits areconnected, the one terminal overlapping the other and the two fitting ina notched rod, said rod terminating in a ring or handle.

In testimony whereof I afd-X my signature, in presence of two witnesses,this 26th day of June, 1886.
